CONCLUSIONS 
Study of the fermentations occurring 
in large masses of organic debris (ba¬ 
gasse) led to the isolation of a species of 
Psilocybe capable of producing fer¬ 
mentation in this product. Mycelia 
were found to penetrate compact areas 
in bagasse where common molds were 
unable to develop. This development 
was extremely rapid and was accom¬ 
panied by easily determinable visual 
changes in the fibrous mass. 
The great activity shown by this 
Psilocybe in pure culture and in the 
field, considered together with the 
abundance of such forms in connection 
with decaying plant remains, suggests 
the need of intensive study of the 
habits and possibilities of the mush¬ 
rooms as agents of decomposition, 
especially in the soil.
